To express the future in the past: “This morningPaul said he willbe going shopping tomorrow“.Ce matin, Paul a dit qu’il ira faire des courses demain. “Last tuesday Paul said he wouldbe going shopping the following day“. Mardi dernier, Paul a dit qu’il irait faire des course le lendemain. As in English we use the conditional to express the future in the past.

3. Would: Past Conditional

If I had gone to that party, I would have had a good time. Si j’étais allé à cette fête, Je me serais bien amusé Here we use to be conditional + past participle (s’amuser needs to be as an auxiliary verb)

If I had heard the weather report, I would have taken an umbrella. Si j’avais entendu la météo, j’aurais pris un parapluie.

As you can see, we use the conditional of the auxiliary verb + the past participle of the following verb, like in English, just be careful with the second auxiliary in French, être.
